The IS on Wm Rogers Silverware stands for International Silver.
Nickel Silver
866 means silver plated sorry
It is nickel silver... no actual silver content.
From my current research into silver I would guess it's the purity. 999 is the purest silver you can find, Sterling is stamped 925, or 92.5% silver. I would guess 963 means 96.3% silver.
it is pure silver
When silver jewelry is stamped 80 SR it means that the jewelry is 80% silver.
if the number .925 is stamped on it also that means sterling silver if the number .999 is stamped on the ring that means it is pure silver if no numbers, i am not sure
The number 966 stamped on William Rogers silver trays indicates the composition of the metal used in the piece. Specifically, it denotes that the item is made of a mixture of silver and other metals, typically containing 92.5% pure silver, with the remainder being other metals like copper. This marking is part of the broader practice of labeling silverware to indicate its quality and authenticity. William Rogers was known for producing silver-plated items, so the 966 stamp helps identify the specific grade of silver used in the tray.
The I S stands for International Silver Company Meriden, Connecticut.
